The thing to realize is that IDLE is a TK
application…and so is the turtle graphics. They conflict. There are
apparently workarounds, but I’m not a TK weenie. There’s some
information here: http://rlai.cs.ualberta.ca/RLAI/RLsoftware/PythonLinks.html Consider teaching kids to use a text
editor instead of typing things into IDLE. They can write and save programs and
run them pretty easily. SubEthaEdit is free for noncommercial use and could
even let kids collaborate on writing programs together from separate machines. Try this program, for example: import turtle import random turtle.reset() turtle.down() for i in
xrange(100):
dist = random.randint(5, 15)
angle = random.randint(-135, 135)
turtle.forward(dist)
turtle.right(angle) turtle.up() Save it into a .py file, then run python
on it. Once you get a decent editor set up, it’s
a lot easier and more scalable than monkeying with IDLE anyway. You might also consider something like
PyGame, depending on the sophistication and interests of your students. Kent

[mailto:[EMAIL PROTECTED] On
Behalf Of Neal Carpenter The problem: From within IDLE, I type: I then get a small window,
titled tk, and a new 'console' window. When I move the cursor to either of
these I get a spinning rainbow disk, and am unable to enlarge the tk window.
This does not happen when I use Terminal. I want to use IDLE (for ease of use) and turtle graphics (for
motivation) to teach programming to my 6th, 7th, and 8th graders. Am I doing
something wrong? Is this a problem with IDLE? Is there a fix or a work-around?
(I'm very new to Python myself and have warned my students that I'll be
learning it from them, as they learn from me.) Also, what is the 'Console' window for? I've tried typing in it only to
get error messages. This started while I was using Jack Jensen's IDLE, and Tiger's built-in
Python (2.3.5?); I've spent most of the day searching for a solution and came
upon your name in Pythonmac-SIG. So I got to your site, downloaded and ran
2.4.1 and the TigerPython24Fix, only to find that the exact same thing still
happens - import turtle stuff, invoke any turtle word, and find a small window
that 'works' (the turtle moves around, on command) but that cannot be enlarged
(still the swirling rainbow disk). Thanks for your time - any help would be greatly appreciated.
